Review: Recommended - Really good and easy to use, just be carful after shaking as a lot of paint can come out at once, can be used for all ages, cleans up easy can spread around whilst cleaning up, push down function to release the paint, lasted quite a while
Review: Easy to use - These are quite large. Once you have the paint flowing they are really easy to use, it works really well on glass.. tip get a finer pen for details. ( haven’t tried to remove off glass but will update after Xmas )
